HS-VT Chain block/Vital Chain Block/Hand Chain Blo

ISO 9002 HS-VT series chain blocks 8 characteristics to make chain block have high ability and security,high agility, and this greatly reduced work intension. Gear:they are innovated symmetrical arrayed highspeed synchronous gears,and are made from international standard gear steel. Compared with common gears,they are more wearable and steadier,and more laborsaving. Chain:adopts high strong chain and high precision welding technology,meet ISO3077-1984 international standard;fits for gusty overload work conditions;takes your hands a better feeling;multi-angle operation(with 45°). Hook:made of high-class alloy steel,it has high strength and high security;by using newy desing,weight will never escape. Limit Switch:using limit switch component in designation to protect chain and ensure security. Components:main components are all made of high-class alloy steel,with high precision and security. Framework:slight design and more beautiful;with less weight and smaller work area. Plastic Plating:by adopting advanced plastic plating technology inside and outside,it lookslike a new one after years of operation. Encloser:made of high-classed steel,more firmly and dexterous.
